BP, PR, PP, and nocturnal dipping, by quartiles of day-to-night ratio of urinary sodium and potassium excretion rate. The dots and squares represent means in different quartiles of day-to-night ratio of the urinary sodium excretion and day-to-night ratio of the urinary potassium excretion, respectively. Bars represent interquartile ranges (25th and 75th quartile); dipping represents the nocturnal BP decrease (nocturnal BP minus daytime BP), expressed in percentage of the daytime BP. BP, blood pressure; bpm, beats per minute; DBP, diastolic blood pressure; PP, pulse pressure; PR, pulse rate; SBP, systolic blood pressure.
